Title: Harmonic noise removing device
Inventor: NAGANUMA KAZUTO
IPC: H04N5/21
Filed: 1990-07-11
Abstract: PURPOSE:To make mastering possible by using an obtained signal, and to widen the range of a frequency band to be removed by removing a harmonic noise component by adding the separated harmonic noise component in reversed polarity. CONSTITUTION:A VFM signal outputted from a signal source 31 is inputted to a trap circuit 42 after being limited by a limit circuit 32. After the trap circuit 42 traps a second harmonic wave Jz from the inputted signal, it outputs that signal to an addition circuit 43. Besides, the signal outputted from the limit circuit 32 is supplied to the addition circuit 43 after being delayed by time corresponding to the processing time of the trap circuit 42 by a delay circuit 41. The addition circuit 43 adds (subtracts) the signal inputted from the trap circuit 43 in the reversed polarity to (from) the signal inputted from the delay circuit 41. Thus, the second harmonic wave Jz is separated. The signal outputted from the addition circuit 43 is subtracted from the signal outputted from the limit circuit 38, and the mixed signal of the VFM, an EFM, and an AFM signals free from the second harmonic wave Jz can be obtained.

Filed: 1992-07-09
Abstract: PURPOSE:To reduce noise and to improve overwrite characteristics even by a magnetic disk device of high density recording by making values of track width and core width of a magnetic head core fall within a specific range. CONSTITUTION:A metal magnetic thin film 33 having high saturated flux density is formed on an opposite surface of one core piece 32 out of one pair of Mn-Zn monocrystal ferrite core pieces 32 and 32' of high permeability, which constitute the magnetic head core 31. One pair of core pieces 32 and 32' are jointed with a nonmagnetic material to make a magnetic gap 34, and this conjunction is reinforced with a bonding glass 35. The magnetic head core 31 of the core width Cw is provided with a notch to cope with high desification of the track recording density, so that the track width is regulated to be limited to Tw. Then, the track width Tw and the core width Cw are limited to such a range as 4mum<=Tw<=10mum and (5 to 8)XTwmum<=Cw<=130mum. Consequently, the magnetic head with less noise and good overwrite characteristics can thus be obtained even with a high density recording magnetic disk device in a class of 250 megabits/in<2>.
